Sources: UK House Price Index (HM Land Registry, with the ONS and the Welsh Government), to August 2026; ONS Price Index of Private Rents, to September 2026. Figures for the whole council area, not this street. The typical price is adjusted for the mix of homes that sold, so it is not the value of any one home; the street's own sales are above. Rents are the average paid on all private tenancies, new and existing, so they move more slowly than rents being advertised.

Energy performance certificates

Source: Energy Performance of Buildings Register (MHCLG), register as at 1 November 2026. Latest certificate per address; certificates last ten years, so the oldest here and some homes have none. Address data © Ordnance Survey and Royal Mail, shown for understanding the energy efficiency of buildings only.

No certificates found for addresses on this street.

Gas and electricity use

No gas meters are recorded on the postcode, against 8 electricity meters: it looks to be off the mains gas grid, or almost, with heating from electricity, oil, LPG or solid fuel.

These are all the homes on the postcode, whatever their size and however many live in them, so they show the kind of homes and heating here rather than what any one home uses. The typical figure is the median: half the homes used less. The district is SY25.

Planning and heritage

  • Conservation area: no postcode centre in this street's postcodes is in one.
  • Listed buildings on or by this street: none.
  • Article 4 directions, tree preservation orders and green belt: Wales has no national record of these; the council's planning department holds them.

Source: DataMapWales (Welsh Government): conservation areas compiled from the councils, and Cadw's listed buildings. Conservation areas are checked at each postcode's centre; some councils' boundaries in this layer have not been updated for years, so the council's own map is the one to rely on. Listed buildings are counted on or by this street. Planning applications are not here: there is no national open record of them.

Energy projects nearby

No wind turbine or waste plant within 5 km (3.1 miles), and no solar farm, battery site or other project of 1 MW or more within 2 km (1.2 miles), of the street's postcodes, operating or planned.

Source: Department for Energy Security and Net Zero, Renewable Energy Planning Database, Q2 2026 extract, Open Government Licence: renewable electricity and storage projects over 150 kW, operating, being built, permitted or applied for. Shown: wind turbines and plants that burn or digest waste within 5 km (3.1 miles), other projects of 1 MW or more within 2 km (1.2 miles); refused, withdrawn and abandoned projects are left out. Distances are from the nearest postcode centre to each project's grid reference.

Roadworks

Street works permits come from the Department for Transport's Street Manager, which covers England only.

Source: Department for Transport, Street Manager open data, permits and works up to 31 October 2026. It is published once a month, so works arranged or started since then are not shown, and dates are the ones planned unless the works have started or finished. Emergency works are often permitted after they begin.

Flood risk

Rivers, the sea or surface water: of the 15 address points in this street's postcodes, 3 at high risk, 0 at medium risk and 0 at low risk. Each counts once, at the higher of its rivers-and-sea and surface-water risk.

Rivers and the sea alone: 3 at high risk, 0 at medium risk and 0 at low risk. Surface water and small watercourses alone: none is in an area at risk.

High: 3.3% (1 in 30) or more chance of flooding a year. Medium: 1% to 3.3%. Low: 0.1% to 1%. The map allows for flood defences. Address points are every property record (UPRN) in the postcode, each counted if it is in an area or within 5 m of one (the maps stop at building walls); a few are not homes, such as garages, business units or caravan pitches. Counts cover whole postcodes, which can include other streets.

Flood zone for planning: no postcode centre is in flood zone 2 or 3. Welsh zones include an allowance for climate change.

Recorded floods

No recorded flood covers the centre of this street's postcodes.

Recorded floods are where floodwater was seen or surveyed after a flood. Many floods were never mapped, an outline over a postcode's centre does not mean every home in it flooded, and homes outside one may have. Ask the seller whether the home itself has flooded.

Sources: Natural Resources Wales Recorded Flood Extents; Natural Resources Wales Flood Risk Assessment Wales: rivers, sea and surface water (loaded 30 October 2026), and Flood Map for Planning: rivers and sea (loaded 29 October 2026); address points from OS Open UPRN and the ONS UPRN Directory. Flood zones are checked at each postcode's centre point. These are models of areas, which their publishers say are not suitable for showing whether an individual property is at risk, and they do not cover flooding from sewers or drains.

Coastal erosion

No projected coastal erosion zone is within 1 km (0.6 miles) of the street's postcodes.

Distances are from the nearest postcode centre to the edge of each zone; where a postcode centre is inside a zone, some homes on it may not be.

Storm overflows

No storm overflow outlet is within 1 km (0.6 miles) of the street's postcodes in this record, which covers the overflows reported to the Environment Agency: most of Wales's are reported to Natural Resources Wales instead.

Source: Environment Agency, Event Duration Monitoring storm overflow annual return for 2025, from the water companies' monitors on each overflow in England, Open Government Licence. Distances are from the nearest postcode centre to each overflow's outlet. A year's figures are published the following spring; a monitor that worked for less of the year undercounts.

Coal mining

No postcode centre here is in a coalfield: the Mining Remediation Authority records no coal mining risk here.

Source: Mining Remediation Authority (formerly the Coal Authority), development high and low risk areas, Open Government Licence. Checked at each postcode's centre, so a home near the edge of an area may differ. It covers coal mining only, not other mining (such as tin, lead, iron or chalk), and is no substitute for a coal mining search. About the risk areas.

Radon

The postcode is in a 1 km square with radon potential up to 5 to 10%: up to that share of homes there is estimated to be at or above the Action Level of 200 becquerels per cubic metre. At least part of the square is a radon Affected Area, where 1% or more of homes are.

Radon is a natural radioactive gas from the ground that can build up indoors; long exposure raises the risk of lung cancer. A three-month test with two small detectors is the only way to know a home's level, and a high level can usually be brought down with a sump or better ventilation. Homes built here in recent decades should have radon protection under the building regulations (basic protection from 3%, full protection from 10%). UKHSA sells a radon report for a single address from its detailed map at ukradon.org.

Source: British Geological Survey and UK Health Security Agency, Indicative Atlas of Radon in Great Britain, Open Government Licence. Contains British Geological Survey materials © UKRI 2026. Each 1 km square is classed by the highest radon potential found anywhere in it, so a square's figure can overstate it for much of the square; the detailed map is not open data.

Historic landfill

No historic landfill site is within 500 m (0.3 miles) of the street's postcodes.

Sources: Environment Agency and Natural Resources Wales, historic landfill sites (places where waste was put into or onto the land and no environmental permit is now in force), Open Government Licence. Distances are from the nearest postcode centre to the edge of each site as mapped; the outlines and dates come from old records and can be approximate. Landfill still operating is not included.

Height above sea level

The street's addresses are about 161 m above sea level.

Source: Ordnance Survey, OS Terrain 50, July 2026: the height of the ground on a 50 m grid, read at each address, in metres above Ordnance Datum (mean sea level at Newlyn). It is the lie of the land, not floor or threshold levels, and is accurate to a few metres. Being low-lying is not in itself a flood risk; the flood section above says what the flood maps show.

Air quality

Source: Defra, modelled background air pollution, annual means for 2024, for the 1 km square that holds the middle of the street. These are background levels, away from the kerb: beside a busy road nitrogen dioxide in particular can be several times higher. UK limits are the legal annual limits for England and Wales; the World Health Organization's 2021 guidelines are much stricter, and most towns and cities are above them.

Annual means in µg/m³ (micrograms per cubic metre of air)
PollutantHereUK limitWHO guideline

Road and rail noise

Source: Welsh Government, Environmental Noise Mapping 2022 (Wales), modelled with Defra's noise model for every road and railway in Wales and published in August 2023, through DataMapWales: Lden, the average sound level over a whole day with extra weight for the evening and night, on a 10 m grid, read at each address. These are models of traffic, not measurements; they leave out aircraft, industry and neighbours, and a room at the back of a house is often much quieter than the front. The World Health Organization's guidelines are 53 dB for road traffic and 54 dB for railways.

None of the street's 3 addresses is modelled at 55 dB or more from road traffic or railways.

Climate, daylight and earthquakes

Monthly temperatures and rainfall, sunrise and sunset through the year, and earthquakes recorded nearby since 1970 are much the same across the area, so they are worked out once for Ceredigion: see them on the Ceredigion page.

Nearest schools

Distances are straight lines from the middle of the street to the school; catchments and admissions are not shown. Estyn, which inspects Welsh schools, no longer gives grades; its reports describe each school in words.

No open schools within 2 km (1.2 miles).

Crime within 250 m

Source: data.police.uk street-level crime, September 2025 to August 2026. Police forces move every crime to the nearest of about 760,000 anonymised map points before publishing, so these are crimes near this street, not on it, and a busy point can collect crimes from a wider area. Counts are of records, not convictions.

No crimes recorded at anonymised points within 250 m in this period (Dyfed-Powys Police).

Road safety

Source: Department for Transport, road safety data (STATS19), collisions in 2021 to 2025, as published by November 2026. Collisions in which someone was hurt and which were reported to the police, within 150 m of the middle of any of this street's postcodes, or of the street. Severity is the worst injury as the police recorded it.

No collisions in which someone was hurt were reported on and around the street in 2021 to 2025.

Only collisions in which someone was hurt and which the police were told about are here: damage-only collisions and near misses are not, and some injuries are never reported. Positions are recorded by the police, usually to within a few metres. Each year's figures are published the following September.

Traffic on nearby roads

No traffic count point is within 500 m (0.3 miles) of the street's postcodes. The Department for Transport counts every motorway and A road and only a sample of minor roads, so a quiet residential street usually has none.

People and work

Source: ONS Census 2021, taken on 21 March 2021, for the Output Area (a small census area of about 125 households) that this street's postcodes are in: 316 residents in 149 households. The census was taken during a lockdown, so working from home is high and travel to work low compared with now. ONS swaps a few records between neighbouring areas and adds small amounts of noise to counts to protect privacy, so small differences mean little. Industry is not published for areas this small.

What this page cannot tell you

  • Whether a particular house is at risk of flooding, subsiding or anything else: the flood map is a model of areas and there is no property-level data here.
  • What a home is worth now: sales are historic prices for the homes that happened to sell.
  • How safe the street is: crime points are moved to anonymised locations and many crimes are never reported; road collisions count only those in which someone was hurt and the police were told.
  • Whether you would get a place at a school: distances are straight lines, not catchments.
  • Who lives on the street now: census figures describe the small areas around it in March 2021, during a lockdown.
  • How long a journey takes or how often anything runs: transport distances are straight lines to the nearest stops.
  • Whether a GP practice is taking new patients, or a dentist new NHS patients.
  • How loud a home is inside, or noise from industry, neighbours or smaller airfields: noise figures are models of road, rail and air traffic outside.

How each figure on this page is matched to the street and worked out: methodology.
